How to Select Protective Products Based on Equipment Wear Types
Technical Approach for Selecting Protective Products According to Equipment Wear Types
I. Abrasive Wear Protection
Material Selection
High-vanadium high-speed steel (0.3-1.0mm thickness) with PTFE/POM beveled edge design reduces contact stress
Tungsten carbide coating (≥1.5mm thickness) enhances abrasive wear resistance by 5-8 times
Surface Treatment
Ceramic particle-filled epoxy materials (e.g., Loctite PC 7218) suitable for coarse-particle media zones
Shot peening to form a 0.3mm-deep residual compressive stress layer
II. Adhesive Wear Protection
Optimized Material Pairing
Worm gear sets employing “hard tooth surface + soft tooth surface” combinations (e.g., 40Cr steel worm paired with tin bronze worm wheel)
Modified polyimide (PI)
Worm gear pairs employ “hard tooth surface + soft tooth surface” combinations (e.g., 40Cr steel worm with tin bronze worm wheel)
Modified polyimide (PI) material withstands temperatures from -200°C to 300°C
Lubrication Solutions
Sulfur-phosphorus extreme pressure additive lubricants (ISO VG 320/460)
Molybdenum disulfide dry film lubrication (for operating conditions above 120°C)
III. Fatigue Wear Protection
Structural Design
Minimum transition radius ≥ 1.5 times cross-sectional thickness
Dual-lead worm design enables axial adjustment of backlash
Monitoring and Maintenance
Vibration spectrum monitoring (alarm triggers at >10% abnormal deviation)
Oil particle size inspection every 2000 hours (≤25μm)
IV. Corrosion and Wear Protection
Material Protection
316L stainless steel (Ra≤0.8μm) resistant to chloride ion corrosion
Titanium alloy TA2 passes 96-hour salt spray test
316L stainless steel (Ra ≤ 0.8μm) resistant to chloride ion corrosion
Titanium alloy TA2 passes 96-hour salt spray test
Environmental Control
Cathodic protection potential: -0.85 to -1.05V vs. Cu/CuSO₄
Corrosion inhibitor dosage: 0.1-0.5 wt%
V. Comprehensive Protection Case Studies
Wind turbine main shaft: Carburizing and quenching (58-62 HRC) + online vibration monitoring, tripling service life
Chemical pipeline: Ceramic-metal composite material withstands 200°C organic solvent corrosion
Note: Specific selection requires matching with standard parameters per GB/T 10089, GB/T 20878, etc.
